Abstract
Providing alerts to a user that is participating in a telephone call includes operating a telephone call between a first user and a second user. The telephone call uses a voice path, a first signaling path, and a second signaling. An indication of an alert to be presented to the first user is received. The alert is configured for presentation to the first user on a telephone used by the first user. Control signals are sent from the telephony services provider to the first telephony proxy server over the first signaling path. The control signals are configured to cause the alert to be presented audibly to the first user on the telephone used by the first user such that (i) the first user hears the alert, (ii) the second user does not hear the alert, and (iii) the alert does not obscure other content of the telephone call.
